Abstract

The embodiment of the present disclosure discloses a signal enhancement method and device, a computer-readable storage medium, and an electronic device, wherein the method includes: determining transfer function matrices corresponding to at least two positions in the setting space; The matrix determines a beam filter and a blocking matrix for adaptive filtering; based on the microphone array, the desired signal sent by each position in the at least two positions is respectively collected to obtain an original sound signal; through the beam filter and blocking matrix to process the original sound signal to obtain the desired signal corresponding to each position in the at least two positions. The beam filter and blocking matrix determined based on the transfer function matrix in this embodiment are more suitable for the set space The signal enhancement of the sound source signal improves the enhancement effect of the beam filter on the sound source, and improves the suppression effect of the blocking matrix on the sound source.

Description

technical field [0001] The present disclosure relates to sound signal processing technology, in particular to a signal enhancement method and device, a computer-readable storage medium, and electronic equipment. Background technique [0002] In order to facilitate the recognition and other processing of voices in multiple positions in the set space, it is necessary to enhance the multiple positions respectively to improve the processing effect. Voice information for each seat. However, in addition to the speech signal to be processed in the setting space, there will also be other sound signals (such as noise, etc.). , engine noise, air-conditioning noise in the car, music in the car, and speaker interference in the car, the performance of traditional speech enhancement methods is limited. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present disclosure is proposed. Embodiments of the present disclosure provide a signal ...
